August 6,2003 update -- Desktop copies (Windows, Macintosh, Linux, Unix): NUIT has recently signed a license agreement with Wolfram Research for use of Mathematica on campus. Distribution for Windows and Macintosh workstations has been made through NUIT's "chocolate" server. The annual workstation license fee is expected to be $99; the first year (through August 31 2004) will be covered by a special stipend from NUIT for faculty and staff.

If you access skew4 through Xwindows, then you can type "mathematica"
and get a graphic interface.

Type "math" you will see a terminal window interface

To exit, type: Quit

at the Mathematica prompt

Batch mode:

math < infile > outfile

To run this batch job in the background, and continue to run after logout,
type the following command.

nohup math < infile > outfile &

The infile is a text file composed of the necessary Mathematica input commands
and the outfile is the file that is written by Mathematica that contains
the evaluations of each of the input commands It is sometimes useful to
make the first line in the infile AppendTo[$Echo, "stdout"] so
that the input lines will also be included in the output
file. Also, the input file should always end with an empty
line. (This information
appears on page 32 of the Getting Started with Mathematica for
X/Unix.)

NOTE: a standard Mathematica notebook (.nb) that is saved in the
interactive mode can not be directly used as an input to batch
mode (as opposed to a plain text file with only Mathematica commands
described above). To convert an interactive notebook into a valid
batch input file, use the following procedure:

NOTE: if you want to use MATHEMATICA on skew3 via XWin32, you need to download the latest Mathematica font file (ZIP format). Create a folder in "\Program Files\StarNet\X-Win32\Common\Lib\Fonts" and uncompress the contents of bdf.zip in it. Then. use XConfig to add this new folder to the font paths. The Mathematica font files on Startnet/NU site have not been updated to work with Mathematica V5.

How do I export graphics to EPS/GIF/PBM/WMF format? This is desirable particularly if you run Mathematica in batch mode and want to save the
graphic output for later use. In Mathematica 4.0 and above, the Export function
will do. In the earlier versions, you can use Display function: http://support.wolfram.com/mathematica/graphics/export/
